The castration level of testosterone and hormonal resistance of prostate cancer in androgen deprivation therapy

Serum testosterone level predicts the effective time of androgen deprivation therapy in metastatic prostate cancer patients

Androgen deprivation therapy (ADT) is the standard of care for patients with metastatic prostate cancer. However, whether serum testosterone levels, using a cut-off point of 50 ng dl-1 , are related to the effective time of ADT in newly diagnosed prostate cancer patients remains controversial. Moreover, recent studies have shown that some patients may benefit from the addition of upfront doceta...

Androgen Deprivation Therapy for Prostate Cancer

AN D R O G E N D E P R I V A T I O N t h e r a p y ( A D T ; h e r e i n defined as medical or surgical castration) is the cornerstone treatment of advanced prostate cancer. In 1941, Huggins and Hodges first noted the beneficial effects of castration and injection of estrogens in patients with metastatic prostate cancer. The biological basis of the effect of ADT, the almost ubiquitous expressio...

Study of testosterone-guided androgen deprivation therapy in management of prostate cancer.

BACKGROUND Androgen deprivation therapy (ADT) with luteinizing hormone releasing hormone (LHRH) agonists is an effective initial therapy for men with advanced prostate cancer. LHRH agonists are usually administered indefinitely at a fixed interval. METHODS We recruited men with advanced prostate cancer who had been on fixed-schedule injections of an LHRH agonist for ≥1 year and had castrate s...

Androgen deprivation therapy for prostate cancer.

CONTEXT Prostate cancer is the most common nonskin cancer and second most common cause of cancer mortality in US men. Androgen deprivation therapy (ADT), specifically surgical or medical castration, is the first line of treatment against advanced prostate cancer and is also used as an adjuvant to local treatment of high-risk disease. OBJECTIVE To review systematically the evidence on the risk...
